摘　　要：针对某金矿以自然金存在、且嵌布粒度粗细不均匀的矿石性质,采用重-浮联合工艺回收金.先用摇床重选获得粗粒金,再用浮选回收细粒金.对原矿Au品位为5.37g/t的矿石,可获得金精矿品位100.21g/t、回收率97.88%的较好指标.In view of a gold ore containing natural gold with dissemination size with non-uniform distribution,ajoint process of gravity separation and flotation was employed for recovering gold.The coarse gold particles were obtained with gravity separation,and then the fine gold particles were obtained with flotation.When the grades of the crude ore were Au 5.37g/t,very good technical indexes such as gold concentrate grade Au 100.21g/t,recovery 97.88% were obtained.
